struct ContentView: View {
    @State private var pt: CGPoint = .zero
    var body: some View {
        let myGesture = DragGesture(minimumDistance: 0, coordinateSpace: .global).onEnded({
            self.pt = $0.startLocation
        })

        // Spacers needed to make the VStack occupy the whole screen
        return VStack {
            Spacer()
            Text("Tapped at: \(pt.x), \(pt.y)")
            Spacer()
            HStack { Spacer() }
        }
        .border(Color.green)
        .contentShape(Rectangle()) // Make the entire VStack tappabable, otherwise, only the areay with text generates a gesture
        .gesture(myGesture) // Add the gesture to the Vstack
    }
}
